Default Re: Air pump/Diverter Problem?

Thanks fdryer.
I just went out and pulled the relay and found the pin out on the relay. It's raining hard right now, but as soon as i can, i will begin to troubleshoot. Thinking maybe installing the jumper to verify the pump will run, if it doesn't, maybe a ground problem? If it does run, check coil voltage with the ignition on. Maybe a bad coolant temperature sensor? Sound like plan?
